A planter box is bought for a different reason than a pot. It is chosen when the planting has to follow a line that already exists in the space, along a wall, a terrace edge, a boundary or a run of glazing, and when the alternative is building something in.
A box draws a line; a pot marks a point
The choice between a box and a round is not decoration. A box sits flush against a wall, aligns with a paving joint and repeats into a run without leaving gaps. A round planter cannot do any of those things, which is why boxes do the structural work on terraces, entrances and roof decks.
Sized by what goes in, not by what it looks like
Every size here publishes its interior length, width and depth as well as the exterior footprint, so the planting can be planned before the box arrives. The longer boxes are also the ones that take a hedge or a grass run rather than a single specimen, which is usually the reason a buyer wanted a box in the first place.
Light enough to place where concrete cannot go
These are hand-laid fiberglass composite, so a 60 in box weighs a fraction of the same shape in concrete. That is what makes a long box viable on a balcony, a podium deck or a suspended slab where the load is capped. Each size lists its own weight.
Made to order, in the finish you specify
Jay Scotts boxes are finished to order rather than picked from a warehouse, which is why the finish range is open rather than whatever happens to be in stock. Allow the published production window on top of transit when planning against an install date.
